In the present work, sheets of Papyrus (Cyperus papyrus L.), manufactured by lamination\nfrom strips pre-treated with different treatments, were evaluated for their technological and fungal\ninfestation properties (Aspergillus flavus AFl375, A. niger Ani245 and Colletotrichum gloeosporioides\nCgl311). The results showed that the highest values of tensile strength, tear strength, burst index\nand double-fold number were observed in papyrus sheets produced from strips treated with\nnano-cellulose (0.25%), dimethyl sulfoxide (DMSO 10%), Tylose (0.25%) and nano-cellulose (0.5%),\nwith values of 98.90 N.m/g, 2343.67 mN.m2/g, 1162 kpa.m2/g and 8.33, respectively. The percentage\nof brightness ranged from 49.7% (strips treated with KOH 2% + 100 mL NaClO) to 9.6% (strips treated\nwith Eucalyptus camaldulensis bark extract 2%), while the percentage of darkness ranged from 99.86%\n(strips treated with Salix babylonica leaf extract 2% or E. camaldulensis bark extract 0.5%) to 67.26%\n(strips treated with NaOH (2%) + 100 mL NaClO). From the SEM examination, sheets produced from\ntreated strips with extracts from P. rigida and E. camaldulensis or S. babylonica showed no growths of\nA. flavus and C. gloeosporioides. Additionally, other pre-treatments, such as Nano-cellulose+Tylose\n0.5% (1:1 v/v) and Tylose 0.5%, were also found to have no growth of A. niger. In conclusion,\nstrips pre-treated with nanomaterials and extracts were enhanced in terms of the technological and\nantifungal properties of produced Papyrus sheets, respectively.
